Gliding is a power based on the sun and flying in the sky. Here are the techniques:
First technique: you can activate an elytra form.
Second technique: while in elytra form, you can dash forward.
Third technique: you can summon a sun spear.
Ultimate:
While sneaking: all entities in a radius around you receive a strength boost and get healed.
Otherwise: you receive a stronger boost and get healed more than if you were sneaking.
Item: Glide Anchor
It's a block that only you can activate. When activated, you can fly freely within a 3-block radius. If you feed it a sun rune, the radius expands to 20 blocks for 5 minutes.
